BACKGROUND [0001] The invention relates to connectors, and especially to a connector for coaxial cables. [0002] U.S. Pat. No. 4,925,403 to Zorzy and U.S. Pat. No. 6,827,608 to Hall et al., which are incorporated herein by reference in their entirety, show connection devices for coaxial cables. In each of those devices, one connector has a center pin, formed as an extension of the center conductor of a coaxial cable, surrounded by a tubular metal shroud. The mating connector has a center socket surrounded by a dielectric component, which is surrounded by a metal sleeve with a clearance between the dielectric component and the sleeve. The sleeve is slotted at its distal end to form a ring of tines or beams joined together by an unslotted base part of the sleeve. The tines are resilient, and when the sleeve is inserted into the shroud, thickened tips on the tines snap into a groove or trepan formed inside the shroud. The connected sleeve and shroud form the electrical connection for the shroud of the coaxial cable. [0003] With this form of connection device as generally used, proximal or base ends of the slots in the sleeve are exposed through a gap between the sleeve and the distal end of the shroud. As a result, water and other contaminants can enter the connection, and can penetrate the space between the sleeve and the center conductor. Contaminant penetration can cause corrosion of the connection device, loss of electrical continuity either directly from contaminant penetration or from the formation of corrosion products, and changes to the electrical impedance of the connection that may interfere with the transmission of signals along the coaxial cable. In addition, the lack of physical continuity of the conductive shroud due to the slots, especially if the two halves of the connection device are not precisely coaxial so that the slots form an asymmetrical pattern, can allow unacceptable levels of signals to radiate to the external environment. The radiating signal may cause interference with neighboring devices, and the loss of signal energy may impair signal transmission along the coaxial cable. SUMMARY [0004] According to one embodiment of the invention, there is provided a connector, comprising a sleeve having axially extending slots at a distal end to define tines yieldable resiliently inward, and a resilient seal encircling the sleeve proximally of the slots. [0005] According to another embodiment of the invention, there is provided a connector, comprising a sleeve having axially extending slots at a distal end to define tines yieldable resiliently inward, wherein the tines are stepped along their length. [0006] According to another embodiment of the invention, there is provided a connection device, comprising a first connector having a sleeve with axially extending slots at a distal end to define tines yieldable resiliently inward and a resilient seal encircling the sleeve proximally of the slots and a second connector having a shroud dimensioned to receive the distal end of the first connector sleeve within the shroud and to engage the first connector resilient seal when the sleeve is fully received within the shroud. [0007] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS [0008] The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention. [0009] In the drawings: [0010] FIG. 1 is an axial section through a pin coaxial connector according to an embodiment of the invention. [0011] FIG. 2 is an axial section through a socket coaxial connector according to an embodiment of the invention. [0012] FIG. 3 is an axial section through a connection device comprising a pin coaxial connector according to FIG. 1 and a socket coaxial connector according to FIG. 2 connected together. [0013] FIG. 4 is a perspective view of part of the socket coaxial connector shown in FIG. 2. [0014] FIG. 5 is a view similar to FIG. 1 of an alternative form of pin coaxial connector. [0015] FIG. 6 is an axial section through part of an alternative form of socket coaxial connector. DETAILED DESCRIPTION [0016] Reference will now be made in detail to various embodiments of the present invention, examples of which are illustrated in the accompanying drawings. [0017] Referring to the drawings, and initially to FIGS. 1 and 2, one form of connection device according to an embodiment of the invention, indicated generally by the reference numeral 20, comprises a pin coaxial connector 22 (shown in FIG. 1) and a socket coaxial connector 24 (shown in FIG. 2). [0018] Referring to FIG. 1, the pin coaxial connector 22 may be a panel mount connector arranged to be mounted on or through the wall of an electronics module (not shown). The pin coaxial connector 22 comprises a central pin 26, which is mounted in a dielectric 32 that is received in a bore 33 of a metal shroud 34 coaxial with the central pin 26. The shroud 34 may be electrically bonded to the wall of the electronics module, or may be carried through the wall in an insulating bushing (not shown). The fittings for attaching the connector 22 to the electronics module may be conventional and, in the interests of simplicity, are not shown in FIG. 1. Various methods of attaching the connector 22 to the electronics module are known, and in the interests of conciseness will not be further described here. [0019] The inside of the shroud 34 has a cavity 36 into which the central pin 26 projects. The cavity 36 terminates at a reference plane 38 defined partly by the cut end of the dielectric 32, and partly by a flat, radially extending wall 40 of the shroud 34, extending outward from the bore 33. [0020] The cavity 36 is rotationally symmetrical about the axis defined by the central pin 26. From the reference plane 38 toward the distal end of the connector 22, the cavity 36 is defined by a trepan 42, a ramp 44 sloping inward from the trepan, a neck 46 smaller than the trepan 42 and slightly larger in diameter than the bore 33, a lead-in taper 48 that widens from the neck 46 towards the distal end, and a cylindrical stabilizer section 50. The distal end of the shroud 34 is formed by a seal lip 52 defining the outermost part of the stabilizer section 50. Continue reading about Cable interconnect...
